Fungicides The Effect Is Remarkable
Oct 25, 2017

Use fungicides to fill the root of the following points:

First, the use of bacterial fertilizer has been used as far as possible without fungicide irrigation root disease prevention. For the use of bacterial fertilizer, the use of bacteria in the bacteria after the bacteria to kill, Fungicides so that fertilizer loss of fertilizer. If the crop has been disease, you must use fungicides irrigation roots, do not consider the bacteria in the biological bacteria are injured, so as to avoid small loss, Fungicides leading to disease outbreak.

Second, after a few days of irrigation within the shed do not pour water. Immediately after pouring irrigation water, will reduce the concentration of liquid, affecting the control effect. So in the fungus irrigation within a few days as much as possible do not pour water, if the lack of water, you can slide in the planting ditch a small water to the ridge to ridge 1/3 is appropriate, pay attention not to diffuse ridge , Fungicides So as not to dilute the concentration of liquid in the soil.

Third, the use of fungicides after irrigation, once the wilting, yellow, stop and other symptoms of injury should be promptly remedy. Immediately poured a water to dilute the concentration of liquid in the soil, in time with the first root of the United States or the United States and more expensive spray irrigation irrigation root, Fungicides the solution of injury, restore the growth of plants significantly.

 Fungicide injury occurs for a variety of reasons, the general water-soluble drugs prone to phytotoxicity. In addition, the sensitivity of different crops to pharmaceuticals is different. Fungicides At the same time, the response of the crop to the pharmacy at different growth stages is different. The general seedling and booting stage are easy to produce phytotoxicity.

Reminder: phytotoxicity and meteorological conditions such as temperature, sunshine, etc. have a certain relationship, the general high temperature and drought, strong sunshine or fog, Fungicides high humidity and other conditions can easily cause crop damage.

Reasonable preparation of the concentration of fungicide spray application, the need to dilute into the appropriate concentration, the concentration is too high can easily cause phytotoxicity, Fungicides but the concentration is too low, then the drug can not achieve the effect of disease prevention and treatment.

The spray quality of the fungicide includes the amount of medication and the quality of the spray. Not because of excessive medication to increase costs, resulting in injury, and not because of too little medication can not achieve the purpose of medication. Spraying the requirements of the fine point of fine, Fungicides uniform, to spray the plant stem and leaves on the positive and negative, and strive to do not leak spray.

General sulfur preparations are mainly used in lime sulfur and barium polysulfide, etc., should be used in the pre-germination of lime sulfur or barium polysulfide is a clear way to clear the Qing garden measures, but the use of grape growing Note that the concentration should be moderate, Fungicides to avoid the impact on the environment.

In the use of copper preparations, we can use Bordeaux fungicide, this agent is mainly to prevent downy mildew, black pox disease, anthrax, brown spot and other effective, but the effect is a bit unstable, the same Pay attention to the concentration, the concentration is too large will affect the leaves, affecting photosynthesis.

For EBDC fungicides, can be divided into domestic and imported. Fungicides The domestic can choose Dai Sen zinc, dexamethasone, mancozeb and other drugs, the domestic EBDC fungicide use of excessive pollution will affect the environment grape safety, Fungicides generally in the latter should be cautious or prohibit the use of imported EBDC fungicide safety is better, the grapes will not cause harm, can be used throughout the grape growing season, mixed with a lot of insecticide fungicide, have a certain synergistic effect.
